[ovirt-users] FOSDEM 2020 - AMENDMENT In Memory of our Friend, Lars Kurth

[Doron Fediuck]

Hi all,
For those of you who are unaware of this, Lars Kurth from the Xen project
has passed away [1]. Lars was one of the people who truly practiced open
source and worked with the oVirt project on running FOSDEM's Virtualization
and IaaS room in the past years.

In Lars' memory there will be a special session [2] on Sunday morning,
which will be broadcasted live. You're all welcomed to join physically or
via the live stream.

Thanks,
Doron

[ovirt-users] Re: The built in group Everyone is troublesome.

[Doron Fediuck]

Just for the record, oVirt has a VM Portal which enables this use case
without a need to change the permission.

[ovirt-users] [FOSDEM] Virtualization and IaaS Devroom CFP extended to December 07

[Doron Fediuck]

Hi all,
the call for papers for the Virtualization and IaaS room is extended until
December 7 midnight UTC. All other dates remain the same as you can read
below.

On behalf of oVirt and the Xen Project, we are excited to announce that the
call for proposals is now open for the Virtualization & IaaS devroom at the
upcoming FOSDEM 2018, to be hosted on February 3 and 4, 2017.

This year will mark FOSDEM’s 18th anniversary as one of the longest-running
free and open source software developer events, attracting thousands of
developers and users from all over the world. FOSDEM will be held once
again in Brussels, Belgium, on February 3 & 4, 2018.

This devroom is a collaborative effort, and is organized by dedicated folks
from projects such as OpenStack, Xen Project,, oVirt, QEMU, and
Foreman. We would like to invite all those who are involved in these fields
to submit your proposals by December 1st, 2017.

About the Devroom

The Virtualization & IaaS devroom will feature session topics such as open
source hypervisors and virtual machine managers such as Xen Project, KVM,
bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as
Apache CloudStack, OpenStack, oVirt, QEMU, OpenNebula, and Ganeti.

This devroom will host presentations that focus on topics of shared
interest, such as KVM; libvirt; shared storage; virtualized networking;
cloud security; clustering and high availability; interfacing with multiple
hypervisors; hyperconverged deployments; and scaling across hundreds or
thousands of servers.

Presentations in this devroom will be aimed at developers working on these
platforms who are looking to collaborate and improve shared infrastructure
or solve common problems. We seek topics that encourage dialog between
projects and continued work post-FOSDEM.

Important Dates

Submission deadline: 07 December 2017
Acceptance notifications: 14 December 2017
Final schedule announcement: 21 December 2017
Devroom: 03 and 04 February 2018 (two days- different rooms)

Submit Your Proposal

All submissions must be made via the Pentabarf event planning site[1]. If
you have not used Pentabarf before, you will need to create an account. If
you submitted proposals for FOSDEM in previous years, you can use your
existing account.

After creating the account, select Create Event to start the submission
process. Make sure to select Virtualization and IaaS devroom from the Track
list. Please fill out all the required fields, and provide a meaningful
abstract and description of your proposed session.

Submission Guidelines

We expect more proposals than we can possibly accept, so it is vitally
important that you submit your proposal on or before the deadline. Late
submissions are unlikely to be considered.

All presentation slots are 45 minutes, with 35 minutes planned for
presentations, and 10 minutes for Q&A.

All presentations will be recorded and made available under Creative
Commons licenses. In the Submission notes field, please indicate that you
agree that your presentation will be licensed under the CC-By-SA-4.0 or
CC-By-4.0 license and that you agree to have your presentation recorded.
For example:

"If my presentation is accepted for FOSDEM, I hereby agree to license all
recordings, slides, and other associated materials under the Creative
Commons Attribution Share-Alike 4.0 International License. Sincerely,
."

In the Submission notes field, please also confirm that if your talk is
accepted, you will be able to attend FOSDEM and deliver your presentation.
We will not consider proposals from prospective speakers who are unsure
whether they will be able to secure funds for travel and lodging to attend
FOSDEM. (Sadly, we are not able to offer travel funding for prospective
speakers.)

Speaker Mentoring Program

As a part of the rising efforts to grow our communities and encourage a
diverse and inclusive conference ecosystem, we're happy to announce that
we'll be offering mentoring for new speakers. Our mentors can help you with
tasks such as reviewing your abstract, reviewing your presentation outline
or slides, or practicing your talk with you.

You may apply to the mentoring program as a newcomer speaker if you:

Never presented before or
Presented only lightning talks or
Presented full-length talks at small meetups (<50 ppl)

Submission Guidelines

Mentored presentations will have 25-minute slots, where 20 minutes will
include the presentation and 5 minutes will be reserved for questions.

The number of newcomer session slots is limited, so we will probably not be
able to accept all applications.

You must submit your talk and abstract to apply for the mentoring program,
our mentors are volunteering their time and will happily provide feedback
but won't write your presentation for you!

If you are experiencing problems with Pentabarf, the proposal submission
interface, or have other questions, you can email our devroom mailing
list[2] and we will try to help you.

How to Apply

In addition to agreeing to

[ovirt-users] FOSDEM 2018 - CFP is about to close!

[Doron Fediuck]

Hi all,
FOSDEM 18's Virt and IaaS CFP ends on Friday!
This is your last chance to submit your session, so do not wait any longer.
You can find more details in [1].

Thanks,
Doron

[Doron Fediuck]

On behalf of oVirt and the Xen Project, we are excited to announce that the
call for proposals is now open for the Virtualization & IaaS devroom at the
upcoming FOSDEM 2018, to be hosted on February 3 and 4, 2017.

This year will mark FOSDEM’s 18th anniversary as one of the longest-running
free and open source software developer events, attracting thousands of
developers and users from all over the world. FOSDEM will be held once
again in Brussels, Belgium, on February 3 & 4, 2018.

This devroom is a collaborative effort, and is organized by dedicated folks
from projects such as OpenStack, Xen Project,, oVirt, QEMU, and
Foreman. We would like to invite all those who are involved in these fields
to submit your proposals by December 1st, 2017.

About the Devroom

The Virtualization & IaaS devroom will feature session topics such as open
source hypervisors and virtual machine managers such as Xen Project, KVM,
bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as
Apache CloudStack, OpenStack, oVirt, QEMU, OpenNebula, and Ganeti.

This devroom will host presentations that focus on topics of shared
interest, such as KVM; libvirt; shared storage; virtualized networking;
cloud security; clustering and high availability; interfacing with multiple
hypervisors; hyperconverged deployments; and scaling across hundreds or
thousands of servers.

Presentations in this devroom will be aimed at developers working on these
platforms who are looking to collaborate and improve shared infrastructure
or solve common problems. We seek topics that encourage dialog between
projects and continued work post-FOSDEM.

Important Dates

Submission deadline: 01 December 2017
Acceptance notifications: 14 December 2017
Final schedule announcement: 21 December 2017
Devroom: 03 and 04 February 2018 (two days- different rooms)

Submit Your Proposal

All submissions must be made via the Pentabarf event planning site[1]. If
you have not used Pentabarf before, you will need to create an account. If
you submitted proposals for FOSDEM in previous years, you can use your
existing account.

After creating the account, select Create Event to start the submission
process. Make sure to select Virtualization and IaaS devroom from the Track
list. Please fill out all the required fields, and provide a meaningful
abstract and description of your proposed session.

Submission Guidelines

We expect more proposals than we can possibly accept, so it is vitally
important that you submit your proposal on or before the deadline. Late
submissions are unlikely to be considered.

All presentation slots are 45 minutes, with 35 minutes planned for
presentations, and 10 minutes for Q&A.

All presentations will be recorded and made available under Creative
Commons licenses. In the Submission notes field, please indicate that you
agree that your presentation will be licensed under the CC-By-SA-4.0 or
CC-By-4.0 license and that you agree to have your presentation recorded.
For example:

"If my presentation is accepted for FOSDEM, I hereby agree to license all
recordings, slides, and other associated materials under the Creative
Commons Attribution Share-Alike 4.0 International License. Sincerely,
."

In the Submission notes field, please also confirm that if your talk is
accepted, you will be able to attend FOSDEM and deliver your presentation.
We will not consider proposals from prospective speakers who are unsure
whether they will be able to secure funds for travel and lodging to attend
FOSDEM. (Sadly, we are not able to offer travel funding for prospective
speakers.)

Speaker Mentoring Program

As a part of the rising efforts to grow our communities and encourage a
diverse and inclusive conference ecosystem, we're happy to announce that
we'll be offering mentoring for new speakers. Our mentors can help you with
tasks such as reviewing your abstract, reviewing your presentation outline
or slides, or practicing your talk with you.

You may apply to the mentoring program as a newcomer speaker if you:

Never presented before or
Presented only lightning talks or
Presented full-length talks at small meetups (<50 ppl)

Submission Guidelines

Mentored presentations will have 25-minute slots, where 20 minutes will
include the presentation and 5 minutes will be reserved for questions.

The number of newcomer session slots is limited, so we will probably not be
able to accept all applications.

You must submit your talk and abstract to apply for the mentoring program,
our mentors are volunteering their time and will happily provide feedback
but won't write your presentation for you!

If you are experiencing problems with Pentabarf, the proposal submission
interface, or have other questions, you can email our devroom mailing
list[2] and we will try to help you.

How to Apply

In addition to agreeing to video recording and confirming that you can
attend FOSDEM in case your session is accepted, please write "speaker
mentoring program application" in the "Submission

Re: [ovirt-users] After upgrading to 4.1.4 unable to start VM or migrate them

[Doron Fediuck]

Yes, none is a valid policy assuming you don't need any special
considerations when running a VM.
If you could gather the relevant log entries and the error you see and open
a new bug it'll help us
track and fix the issue.
Please specify exactly from which engine version you upgraded and into
which version.

Re: [ovirt-users] [Ovirt 4.0] Cluster : Scheduling policy

[Doron Fediuck]

Hi Rohit,
You have 2 ways to handle this case;

1. Use pin to multiple hosts [a]. This will force the VM to run on one of
the hosts you specify (1 or 2).
If the VM is defined as highly available, it'll automatically be restarted
on the other host in case the
current one goes down.

2. Use affinity labels [b]. You would like to set a hard affinity to host
1, and a soft affinity to host 2
to ensure host 1 is chosen if it's up.

HTH,
Doron

Re: [ovirt-users] Very poor GlusterFS performance

[Doron Fediuck]

Hi Sven,
libgfapi is not fully operational yet.
There's some additional work which just got merged[1] in order to enable it.
Hopefully it'll be included in one of the next releases.

Re: [ovirt-users] Watchdog device

[Doron Fediuck]

Hi Gary,
this is a known issue we're working on. if the VM is down it should
work as expected (edit the VM and close the dialog).
Please try and let me know. Another option is to do this until the bug
is resolved is using the REST API.

Note that this is currently working on on Linux guests (there are no
updated Windows drivers). You will need to configure
the device in the guest as explained by the docs.

hosted engine is using SanLock to protect the engine VM disks, which allows
only this VM storage
based fencing. There's work[1] being done to allow this to more VMs, but it
still reuiqres more work.
So for now you should be using host fencing only.

Hi Styve,
Pass-Through Host CPU is irrelevant unless you have a specific CPU flag you
need to utilize.
So I suggest you refrain from using it.
As for NUMA, it works well as long as it's not interleaving. Here as well
you  should use it only
if you understand how it should be used. Otherwise the safe option for you
is vCPU pinning.
Can you please check your logs to see who is creating these threads and
share it?

Re: [ovirt-users] How can I to add RAM to Hosted Engine VM?

[Doron Fediuck]

The right way is simply to edit the hosted engine VM memory settings from
the admin UI.
The file is not meant to be edited and may lead to issues in your setup.

In the past we had Joop coming with his cool setup.
We used it in the booth to demo live migration.

Does anyone wish to do the same this year?

This is awesome, Rene.

I't would be really great to meet more people this year
to get a chance for a f2f talks on oVirt.

Re: [ovirt-users] Getting event message "The Hosted Engine Storage Domain isn't Active" every two hours

[Doron Fediuck]

Hi will,
assuming this is a fresh install (please let us know if this is not the
case), then this is just noise.
In 3.6 the hosted engine VM is being imported into it's own DB, but there's
no active domain
when you start. This is the cause for the noise, and we're working on
improving it.

Re: [ovirt-users] oVirt on Dell SC1435

[Doron Fediuck]

Hi Michael,
the fact that your CPU supports VT does not mean it's enabled in the BIOS.

Reboot the machine and into the security -> virtualization settings. Make
sure
it's enabled there.

One more thing you want to verify is that the kvm module is loaded into the
kernel-
lsmod | grep kvm

You can also run: dmesg | grep kvm
In most cases you'll find something like kvm: some  error if it's disable
by the bios.

Re: [ovirt-users] Reply: host xxx did no satisfy internal filter Memory because its swap value was illegal.

[Doron Fediuck]

Hi,
Glad to hear all is well now. Just to recap regarding your question;

All the values you mention are measured for every scheduling decision.
The conclusion I gave you is based on the code. The actual numbers may
vary so unless you check the values while the scheduler is working, every
number we use is an approximation and it's hard to provide an exact numeric
result other than the formula.

Take care and happy new year,
Doron

oVirt live is running in memory as a live CD. Anything you do will be gone
once the machine power off. So you may want to decide if this is right for

You can restart vdsmd, but it may not do anything (running VMs are

Re: [ovirt-users] GlusterFS Hyperconvergence

[Doron Fediuck]

Hey,

As for libgfapi, there are several uses for it in oVirt, not all fully
implemented at his point. However, you need to remember that this is an
optimization so whenever it's ready it will be release (as a part of the
relevant version) but not having it is still not lacking any functionality.

Per your question, we usually recommend working with replica-3 in hosted
engine scenario. I'd stick to this mode even without HE to ensure you
have replicas as well as quorum in case of a failure. In this mode you
can loose the first host and keep running with replica. Loosing the 2nd
host will cause the FS to become read only. This is double failure which
is pretty impressive for a community project.

Finally, HA is leveraging fencing to ensure we do not start an HA VM on
a host while it's still running on the old host and cause a split brain.
If we do not wish to fence bricks yet still use HA you need to manually
approve each time something happens that host has been rebooted which
kind of make this a manual mode and less highly available.

Hi,
most of the current work is focused in hyperconverged using hosted engine and
this includes the installation and a few other features such as not fencing 
hypervisors
to avoid killing running bricks.
If you do not want to use hosted engine, then you should be able to create 
bricks
and manage them as a gluster volume which your setup should be able to work 
with.
If you do not use HA and/or fencing you should be mostly ok with this use case.

Anything specific you're looking for?

Hi Daniel,
going forward we will have a default profile which will prevent such issues.
So for now I'd advise you simply to create a profile if needed as a workaround.

Hi Daniel,
there are bugs reported for CPU profile, such as [1].
If this is indeed the case (profile error) it should appear
as an error in the engine.log (which may have rotated).

Hi,
I'd advice against manual updates in the DB.
The engine has in-memory cache for quota changes which may miss your
updates.

Hi Paf1,
The metadata issue is not the real problem. It is fixed as a part of-
https://bugzilla.redhat.com/show_bug.cgi?id=1181157

The engine itself does not allow running a VM on a swapping host, so
such hosts will not be used to run new VMs.

Adding folks from the Gluster community to review the swap and other
issues.

Hi Hans,
Some general notes;
First of all it would be best to separate the optimizer to a different
machine, even if a VM. This is needed since the optimizer is based on
OptaPlanner which uses all the memory it can get for optimizations.

To the point this is either something going wrong in the installation or
an access issue. Access can be caused due to root certificate not
trusted by the browser. If you use
wget https://ovirt.optimizer:8080/ovirt-optimizer/result/
do you get an issue / warning on unknown certificate?

Hosted engine is indeed a special case. We're working on some

In what way? ie- it should be as reliable as you can make it.

If the networks should be recognized by ovirt, then it's wither the UI

Hi Soeren,
this is a symptom of a mismatch with libvirt version.
It will go away once your mom-vdsm and libvirt versions are aligned.

Hi Stein,
Currently we're not enforcing new affinity rules on running VMs.
If you restart the VM or migrate it, affinity rules will apply.

In 3.6.0 we're planning to have active enforcement of new / modified
rules on running VMs.

Hi Martijn,
Can you please provide the QEMU command line, together with kvm and qemu 
version?

This information will be helpful for reproducing the problem. However, if the 
problem is not reproducible on a local setup, we will probably need to ask 
collecting some performance information with xperf tool.

Hi Will,
note that Hosted engine requires replica-3 when using Gluster.

If all goes well, we may see a tighter integration coming in the next
version (will require gluster updates as well).

Indeed so; there's no hardware level interaction in hosted engine.
Once you put the setup in global maintenance the nodes will only monitor
that state. So nothing is expected from the HA agent in case the VM or a
node goes down.

Koen,
this is clear now.
Currently affinity applies to VMs only. For 3.6 we're planning "pin to
hosts"
which will allow you to pin VMs to a group of hosts, such as Datacenter1
hosts
in your case. Until 3.6 will be available (which will take a while), you
can consider
writing a filter module for the ovirt scheduler. Let me know if you need
more
details.

Hi Koen.

VMs cannot move between data centers while still running.
Just to provide some basic concepts in terms of hierarchy, we have:

Data-Center1
|
|\ Cluster A
| |
| |\ Host (a)
| |\ Host (b)
|
|\ Cluster B
| |
| |\ Host (c)
| |\ Host (d)
| |\ Host (e)

Data-Center2
|
|\ Cluster A
| |
| |\ Host (f)
|
|\ Cluster B
| |
| |\ Host (g)
| |\ Host (h)
| |\ Host (i)

As you can see, a host may be a part of a single cluster and a VM
will run on one of the hosts. Live migration can be done between
hosts of the same cluster. The only way to move VM between clusters
and DCs are when the VM is down, in a manual way.

So Affinity works in the cluster level, and the rules are valid for a
specific cluster who currently owns the VM.
In your case if Hyp1 and Hyp3 belong to the same cluster, the affinity
rules will apply every time you start or migrate a VM. However, there's
no rule which is valid for Datacenter1 and Datacenter2.

HTH,
Doron

Re: [ovirt-users] Local storage with self-hosted mode

[Doron Fediuck]

Hi Jason,
if you can live with non-virtualized engine, and willing to manage
several engines by yourself, you can use the all-in-one deployment.
This will install engine and vdsm on a single host.

Re: [ovirt-users] is it possible to run ovirt node on Diskless HW?

[Doron Fediuck]

For standard centos you may see other issues.

For example, let's assume you have a single NIC (eth0).
If you boot your host and then try to add it to the engine,
the host deploy procedure will create try to create a management bridge 
for the VMs using eth0. At this point your host will freeze since your
root FS will be disconnected while creating the bridge.

I've done this ~6 years ago, and it required opening the initrd to handle
the above issue, as well as adding the NIC driver and creating the bridge
at this point. So it's not a trivial task but doable with some hacking.

Hi Arman,
Are you working with ovirt node or standard CentOS?

Note that ovirt node is different as it's works like a live cd-
it runs from memory. In order to save some configurations (such
as networking) the local disk is used.

Re: [ovirt-users] ksmd high cpu usage from almost a week with just one vm running

[Doron Fediuck]

Hi,
First of all you need to remember this is accounting all available memory
cache included, so what you see as 22 may not be what mom is using.
Additionally some of the calculations take time for ksm, so it takes time
for everything to stabilize once you hit a peak.

Re: [ovirt-users] ksmd high cpu usage from almost a week with just one vm running

[Doron Fediuck]

Hi,
you can see all the relevant definitions in mom's ksm policy.
The trigger to run ksm is defined here:
https://github.com/oVirt/vdsm/blob/master/vdsm/mom.d/03-ksm.policy#L23

You can change this setting (in each host you have) to something that
suits your load. We have the below bug opened and hopefully handle it
in one of the next versions.

Re: [ovirt-users] Local storage with self-hosted mode

[Doron Fediuck]

Hi Jason,
Hosted Engine was designed to work with a shared storage since all hosts
need to share information on their status, and by that support high-availability
for this VM.

If you do not need high-availability you can use RHEV appliance to get a VM
running with the engine inside. Remember that failure of this host will kill
the engine VM as well.

You should verify your configuration first. If it looks fine consider selinux

Re: [ovirt-users] How to stick VM to hosts?

[Doron Fediuck]

Just for the record, affinity deals with the relation
between VMs, and pinning is about the relation between
a VM and a host.

We're considering extending affinity to handle hosts
as well, but it's not a trivial change.

Hi,
it seems that the optimizer is not getting information
from the engine DB, or the UI plugin cannot connect the
Optimizer.
Do you see any meaningful information in the UI?

Hi John,
oVirt does not choose the qemu version. It uses the one available
in centos[1] or the other relevant distro repo.
Having that said, you need to bare in mind there's a whole stack build on top
of qemu (libvirt, vdsm, etc) and jumping forward may destabilize the setup
you're using.

Well, QoS is per disk. And storage domain is where storage 'meets' the
VM for a specific disk. So from the VM point of view 3.5 cluster level
is required to support the various profiles functionalities.

Very nice!

You can see examples to integration with the scheduler here:

Hi Tibor,
this one is hard to answer;

Current 3.5.0 works with el6 and hypervisors can use el7 as well.

Next one will be 3.6.0 which is in planning stages, so we still do not have
all the details. The general trend is to move to el7 based platform.

So for a community project, you could stay on latest 3.5 stable, but once
3.6.0 will be out, no additional fixes will be provided to 3.5.x, just the
way it is with 3.4.x these days. 

This will cover the time we have from now until 3.6.0 GA, which still has no
final dates. One more thing you want to consider is updates from Centos
for el6. Unsure what happens to 6.5 in a year or so.

Hi,
yes, it should be possible in 3.5.0 to use el7 as a hypervisor.

Punit,
did you set the HT flag in the cluster policy?
See: 
http://www.ovirt.org/OVirt_Administration_Guide#Optimization_Settings_Explained
You should set "Count Threads As Cores" or the engine will ignore your threads.

I believe there's a fix coming for it in 3.5.1. One thing is for sure-
proffered should not be used as a default.

So go ahead and open a BZ for it, and we'll see if we still need to
fix something or have it resolved already and provide the info.

Hi Punit,
we need to do a bit of a research on this one.
In order to make sure we keep track of it, do you mind opening an RFE (BZ)
with all the relevant details, including the hardware that you're using,
guests config, how busy the guests/host are, Which hypervisor is used and
the versions.

Thanks,

Re: [ovirt-users] Cluster settings: "KSM Control" not working?

[Doron Fediuck]

Thanks Frank. 
No need for manual sync if the cluster policy is set, the engine will update 
the police when the host moves to status up.

I wasn't aware of mom.log, thanks! :-) After another host reboot 
and a manual "Sync MOM Policy" it seems like the setting finally came 
through:

2014-10-19 15:57:18,211 - mom.Controllers.KSM - INFO - Updating KSM 
configuration: pages_to_scan:64 run:0 sleep_millisecs:10

Now the ksmd process is still there, but it remains idle.
I've tried this multiple times before upgrading to 3.5.0 GA
today. Maybe it was broken between RC and GA.

I'll keep an eye on this and open a BZ in case the setting will
change again.

Hi Matt,
just a general headsup;
The engine is getting reports on swap usage in the hosts, and by default
will not allow it. This means that no VM will be allowed to start or migrate
to a host actively swapping. It is possible to change it, but highly unwanted
based on past experience.

Hi Frank,
KSM is controlled by MoM, which gets its policy from the engine through
VDSM. MoM will call ksm directly as needed when needed. If you choose
to disable it the policy needs to get updated.
Can you please check your mom logs and see if there are any errors there?

Hi daniel,
Looking into the logs I can see:

(score) Score is 0 due to bad engine health at Sat Sep 27 12:10:56 2014
(start_monitoring) Current state EngineUpBadHealth (score: 0)
(start_monitoring) Best remote host 192.168.50.201 (id: 1, score: 2400)

So it seems that the engine inside the VM is not responding to the health test
hosted engine performs. Can you put the system in global maintenance and
check the engine in the vm? Can you access it from outside the VM?

Hi Daniel,
we're trying to reduce the special features hosted engine has.
The ideal is to have it as every other VM, so I'd rather not
add requirements.
